Four!

A firm pull from Jonny Bairstow dispatches Mohammad Nabi to the ropes. And with that, my work is done for a bit. Matthew Henry will take you through the business end of proceedings.

Some shot to bring up your 50.

Rashid Khan drags it back nicely to end the over, coughing up just two runs.

Afghanistan will have to put mid-wicket back and make him hit over cover. That is such an easy hit for Bairstow since he has such a strong bottom hand.

That's a big 'un!

Jonny Bairstow picks up a full delivery from Rashid Khan and launches the ball into the stands at mid-wicket. My word.

It must help that Bairstow played with Rashid Khan in the IPL and faced him in the nets.

Rashid Khan has his hands on his head as Jonny Bairstow edges the googly into his pads.

Oh, he's picked that one though. Four! That's murderous from Bairstow, hoicking the googly through mid-wicket with a firm swish of the bat.

Jonny Bairstow's fifty came up off 61 balls today. Of the 12 previous times he has reached 50 as opening batsman, this is by far the slowest. 11 of his previous fifties have been reached quicker than run a ball. It has been an uncharacteristically slow half-century from Bairstow.

Some good work from Noor Ali Zadran down on the boundary, diving and palming the ball away from the rope, stops Jonny Bairstow cutting his first ball for four. There's no-one there to do the tidying up, though, and Bairstow and Root jog through for an easy three.

A change of bowling - here's Mohammad Nabi.

A stack of portable toilets are not exactly what you expect to see at an international sports venue. My guess is that a lot of the seating at Old Trafford is temporary, so when the capacity goes up, the need for temporary loos arises.

Joe Root gets his skates on to hurry Jonny Bairstow through for a couple of runs.

Very much a tick-over over from Gulbadin.

Vince's ODI career has followed a similar trend - he has hit no sixes and he has never faced more than 56 balls in an innings.

Jonny Bairstow and Rashid Khan's bromance is my new favourite thing.

Bairstow blocks the leggie's last ball back at him and then grins at Rashid, who is stood, hands on hips, looking deeply unimpressed.

Bairstow has not been free-flowing. I don't think the wicket is quite as quick as it was the other day. But that was a gorgeous cover drive.

He could easily up his scoring rate and have a hundred from 90 balls.

What a shot to get to your half-century!

Jonny Bairtsow drives Gulbadin handsomely through mid-off and holds the pose for the cameras, before acknowledging the applause for his 50. It's come from 61 balls, with five fours and one six.

Joe Root accumulates so quickly. He's got to 24 from 25 balls and I couldn't tell you half of the shots he's played to get there.

My word.

Joe Root goes after Rashid's first ball, trying to hoick him off his hip, and the ball bobbles off the pad and towards the man at short fine leg.

It's Rashid Khan time...
